Abstract

PURPOSE:To attain a side pin correction suitable for any horizontal picture size by varying a side pin correction amount proportionately to the size of a picture. CONSTITUTION:A voltage generated by filtering a vertical parabola waveform 2 and an output from a regulator 3 by means of R1, R2, C2, is inputted to a gain controlled amplifier 4 to let amplifier 4 output a vertical parabola waveform agreed with the horizontal size of a picture. And this output is inputted to the regulator 3 to superimpose a size pin correction voltage on a level of (deflection+B-voltage 1). Thus the size pin correction well agreed with the horizontal size is executed. Therefore, a side pin correction suitable for any horizontal picture size can be attained.
